Challenging chiral EFT with tritium beta decay
D. F. Ramirez Jimenez, S. Heihoff, J. Golak +6
We present a detailed investigation of tritium beta decay up to third order (N2LO) in chiral effective field theory (EFT) using the LENPIC interactions. Unlike existing studies, we…

Three-nucleon force effects in polarization transfers from the doubly spin-polarized initial neutron-deuteron state to the outgoing neutron in neutron-deuteron scattering
H. WitaÅa, J. Golak, R. SkibiÅski +2
We discuss new spin observables presently accessible to measurement in the proton-deuteron (pd) system, namely polarization transfer coefficients from doubly spin-polarized initial…

Estimating theoretical uncertainties of the two-nucleon observables by using backpropagation
K. Topolnicki, R. SkibiÅski, J. Golak
We present a novel approach to calculating theoretical uncertainties in few-nucleon calculations, making use of automatic differentiation via backpropagation, which is particularly…
